I believe Blaris Parish straddled Counties Antrim and Down.
The townland of Broughmore is on the western end of Blaris, almost due east of Lisburn. It is bounded by Lurganure, Maze and Gortnacor.
In Griffith's, there were three John Wilsons and two Jane Wilsons listed in Blaris Parish in 1864:
Johns: Aghnatrisk, Magherageery and Ravernet.
Janes: Carnreagh and Magherageery.
Happy hunting.
